## Long description

The Legrand 042872 is a professional-grade safety isolating transformer engineered to provide reliable power conversion and galvanic isolation in demanding electrical systems. With a power rating of 100VA, this component is designed to step down primary voltages of 230V or 400V to secondary outputs of 24V or 48V, ensuring stable and safe operation for sensitive control equipment.
Advantages
This transformer offers exceptional durability and consistent performance, making it a dependable choice for industrial environments. Its robust construction protects against electrical interference and ensures long-term operational reliability. By providing galvanic isolation, it enhances safety by separating the secondary circuit from the primary power source, which is essential for preventing electrical hazards in control panels and automation systems.
Suitable for
Industrial control panels
Automation and signaling systems
Low-voltage lighting circuits
Safety-critical electrical installations
When it may not be suitable
This transformer is not intended for high-power applications exceeding its 100VA rating. It is also not suitable for outdoor environments unless housed within an appropriate protective enclosure that meets specific IP rating requirements.
Key specifications
Power rating: 100VA
Primary voltage: 230V or 400V
Secondary voltage: 24V or 48V
Function: Safety isolating transformer
How to use
Installation should be performed by a qualified electrician in accordance with local electrical codes. The transformer is typically mounted within a control cabinet or enclosure. Connect the primary input wires to the 230V or 400V terminals as required by your power supply, and connect the secondary output wires to the 24V or 48V terminals depending on the voltage needs of your connected devices. Ensure all connections are secure and that the unit is properly grounded before energizing the system.
What to consider before purchase
Verify that the 100VA power capacity is sufficient for your specific load requirements.
Ensure the input voltage matches your local power grid (230V or 400V).
Confirm that the required output voltage (24V or 48V) is compatible with your equipment.
Check the available space in your control panel for mounting.
Usage recommendations
Always ensure the transformer is installed in a well-ventilated area to prevent overheating. Regularly inspect the terminal connections for tightness and signs of wear during routine maintenance cycles.
